Weird or What?

Im still having trouble figuring out how exactly this video was created. The video suggests that at 5:46 in the morning the streets are flooded with a river of water. Could this be some strange phenomena that occurs in this town? After watching I looked more in depth to the subject and come to the conclusion that the water was digitally placed in during Post Production. With a little hard work and attention to detail, the creators of this video were able to pull off the illusion of a river right in the middle of the town. The audio mixing and sounds for the video really pulled it together, giving it an erie, unsettling feel to it. The subtle camera shakes and pans gives the audience the feeling of actually being there, standing in the water. Its truly amazing to see what other film makers can do with such a simple concept design.
